Crash when using MediaPortal screen blanking

I noticed an issue with WifiRemote/MediaPortal when using screen blanking in MP. Starting media using WifiRemote when the screen is blank trigger strange things. E.g. I got a crash when starting a tv serie when the refresh changes kicked in. Starting playlist track throw a Last.fm error and so on. A workaround that works for me is to send a keystroke before the play command. But it should preferably be handled in WifiRemote.

With my follow-up questions:

Not sure I can follow what exactly the problem is (my MediaPortal setup is pretty basic, no fancy refresh rate changer stuff and the like ;)). We have something in WifiRemote to cancel the screensaver on incoming commands: https://github.com/MPExtended/WifiRemote/blob/develop/Sources/WifiRemote/Core/SocketServer.cs#L575

For this we simulate a left-control-key press. But this isn't what you are after, right?

And his answer to that:

I can check the exact settings in mediaportal config this evening, but I think it's with gui settings. One can reduce framrate or blank screen. Use the blank screen setting and set the timeout to e.g. 5-10 seconds. Then start media through WifiRemote.

The left-control-key press should do the same as I did as workaround with only difference of timing of the commands and a different key. Maybe there need to be a longer delay between the key command and the play command? The workaround worked for me but not for Joost for music playlists, it was he that experienced the problem and I could reproduce it.

I can take a look later to see if one can turn off the screen saver in a better way.
